.i Be it known that I, BENJAMIN R. EAMES, of*y South Newrypin the countyof Oxford andjState `of1 `Maine,` have `invented a new anduseful.Improvement Door-Fastenf ers; and Ildohereby declare that thefol- .Y l owing is a full,`clear, andfeXact description of theconstruction land operation of the same, referencebeing hadto theannexed a drawingLforming part `of this specification, l finwh'ichfg i lFigure lis a sectionof door andjamb,

The "inventionhere `considered belongs to the-class of detachable `doorfasteners, ,made

up `as general features of a part connecting the*` fastener to theframe, with guiding,

bracing and compensating arrangements.

"A," great defect in `most of these fasteners arises from so connectingthe bracewith the C body ofthe fastener as to give it a verticalmovement;` the eect of wear in `most cases being to loosen u thevattachment and `render the brace liable to `fall` of itself.

The designfof thisinvention isto'obviate all` tendency to loosening inthe brace, 4and render the same `capable of performing the doublefunctions `of brace and gage, besides other advantages which will befully set The nature `of the invention consists in constructing themain` body, `or attaching `part of the fastener, of` a bifurcatedhookeda bar, having a triangular brace swung on the rear portion of the barbetween the jaws of a spring compensator, also'movable on `said, `bar sothat by reason jof the horizontal movementofthe brace, it will act as`both "brace and gage while its compression between the jaws of the"compensator will render its motion at `all times suficiently stiff toprevent self action fromloosening.

In the drawing B "isthe body `of the fas- `tener consisting ofthe twohooked legs b connected by the part a. Onthis connecting a portion a,are swung the brace G andcomlips Z` into the jamb I in the manner usualwith such fasteners; the brace G being in theposition shown by red linesin Fig. 5 durmgthe closing of the door D, and thus acting as a certaingage for the position of the att-aching bar. When the door is closed,

and the lips Z driven home, the brace G is thenmoved into the positionshown in Fig. "l, and the door is securely fastened. The

grasping of this brace by the compensator C effectually` prevents itsmovement about a without the application of force on one side; and asthe compensator is a spring no amount of wear can change this stiffnessin the movement of the brace. When the space between the door and jambis wide, the compensator has the position shown in Figs. 3 and 4, whilethe action of the combined gage and brace G is the same.

By this construction of fastener a compact, effective and economicalarticle is produced, and altogether free from the ,disadvantages ofthosenow in use.

. I expressly disclaim hooked` bars with separate and vertically moving`stops and braces, as such -form no part of my invene tion. a But I doclaim as new and of my own inven tionl The herein described combinationof bifur-` cated hooked bar B, spring compensator C, and horizontallymoving brace G, the compensator and brace movable about the verticalconnection of said bar; whereby the self movement of the brace isprevented, while it performs the double function of gage and brace. f

In testimony whereof, I have hereunto signed my name before twosubscribing wit- IIESSGS.

BENJ. E. EAMES.
